ISO7230MDWR

Overview

The ISO7230MDWR is a triple-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It supports unidirectional signal transmission at data rates up to 150 Mbps with a propagation delay of 34 ns. The device provides 2500 Vrms isolation voltage and withstands common-mode transients of 25 kV/µs. Operating on a single power supply between 3.15 V and 5.5 V, it draws 17 mA of quiescent current. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology for noise immunity
• Supports high-speed digital communication with low propagation delay characteristics
• Features robust common-mode transient rejection capability for noisy environments

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits for gate drive isolation

Procurement Notes

Verify the specific ordering suffix matches the required package variant and tape-and-reel quantity. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the procurement channel is authorized to guarantee component authenticity and traceability. Check for any recent product change notices affecting specifications or manufacturing location.

Selection Notes

Select this component when three independent unidirectional channels are required within a single package. Consider the 150 Mbps speed limit and 2500 Vrms isolation rating against system requirements. Evaluate the 16-pin SOIC footprint for PCB layout constraints. Compare power consumption and thermal performance against alternative isolators if efficiency is critical.

Part Context

This part belongs to the ISO7230M series of high-speed digital isolators designed by Texas Instruments. The series focuses on providing reliable signal transmission across isolation barriers while maintaining small form factors. The MDWR suffix indicates a specific tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.

Replacement Considerations

ISO7230MDWRG4 is a verified equivalent variant within the same family offering identical electrical specifications and pinout compatibility.
